A pattern discriminator receives scanning data obtained by raster scanning objects within predefined window regions with a photoelectric converter, converts the scanned data into pixel binary data by using a threshold value dependent upon the scanning position and window region and evaluates the binary data in accordance with predetermined criteria to produce an output signal indicative of the evaluation. A memory stores data which represents the window regions in a compressed arrangement indica...

A tread pattern in which the width and positions of grooves formed annularly in the portion of the surface of the tread which corresponds to the ground-contacting surface of the tire, in such a manner that the grooves extend in the circumferential direction of the tire, are suitably limited.

For the transmission of synchronizing information for a PCM signal transmitted in biphase code, a synchronizing pattern is provided which is composed of a biphase signal that has been shifted by one-half bit period relative to the data portion of the transmitted signal.

A pattern control arrangement for a knitting machine comprising a pattern band, magnetic tape or the like, reading means for reading the band, tape or the like and providing pulses for operation selectors movable into or out of butt-engaging position for controlling the positions of butts on or associated with needles, wherein the reading means includes means to provide pulses for moving selectors into butt-engaging position in accordance with information carried by the band, tape or the like, a...

A mask pattern useful for preventing the pattern distortion caused by light transition is disclosed, including a transmissive substrate; a first light-shielding line pattern formed to have an oblong form on the transmissive substrate; second and third light-shielding line patterns of an oblong form spaced apart from a long side of the first light-shielding line pattern and having a width of narrower than a width of edge portions of the first light-shielding line pattern, wherein a space at right...

A dielectric pattern. On a substrate having a metal wiring layer formed thereon, a first dielectric layer and a first masking layer are formed. A cap insulation layer is formed on the masking layer. The first dielectric layer, the first masking layer and the cap insulation layer are penetrated through by a first opening. A second dielectric layer and a second masking layer are formed on the cap insulation layer. The second dielectric layer and the second masking layer are penetrated through by a...

A pattern injector for testing stations in a data communications network and the physical link between them. The pattern injector replaces normal characters in a normal, unmodified stream with injection characters. The pattern injector includes a multiplexor that receives both a current normal character and the injection character as inputs and provides the injection character as its output upon receipt of a select signal. Selection logic responsive to mode selection inputs selectively provides ...

A data pattern generator in which the address generation of a program counter (11) is controlled in accordance with an operation code and an operand read out of an instruction memory (12'). An address/data pattern is generated in response to an address/data computing instruction read out of the instruction memory (12'). Random logic patterns for testing a logic circuit are prestored in a data buffer memory (18) and are read out therefrom using an address created by an address pointer (19). The a...

A portable illuminated light box is provided for the craft industry such that a pattern may be traced or painted on the fabric of a shirt of other garments. The light box includes a plurality of rechargeable batteries which may be placed upon the side walls of the housing of the light box. The output of the batteries is applied to a low voltage fluorescent light tube having a reflector associated therewith which shines up and through a transparent screen. In one embodiment, the fluorescent light...

A pattern generator comprising a memory for storing a plurality of regular character and sign patterns, an input device for receiving as image data a character and sign pattern in a document, a pattern recognition unit for recognizing the character and sign pattern in the image data that the input device has received, a converter for converting the character and sign pattern recognized by the recognition into to the corresponding character and sign code, and an output device for reading from the...
